To uZ/ who m; 2'2? may concern;

Be it known that I, Gnonon GonnU, a citizen of the United States,residing at Win- Chester, in the county of Middlesex and State oflilassachusetts, have invented certain Improvements in;Fasteninglnserting' Machines, of which the following description, inconnection with the accompanying drawings, is a specification, likereference characters on. the drawings indicating like parts in theseveral figures. M

This invention relates to fastening inserting machines and particularlyto fastening inserting machines employing previously formed fastenings.1

In the type of machine shown in patent to Hoddu, No. 490,624, grantedJanuary 2a, 1893, fastenings are supplied tothe fastening); inserting;mechanismby meansof a hopper mounted on a stationary part of the machineframe and a raceway carried by the oscillatory head, the upper end ofthe race-- way being slid-able in the hopper. When it becomes necessaryor desirable to change the kind of fastenings, being driven, thehopperand the raceway must be emptied andother fastenings substituted. Variousarrangements designed to facilitate emptyingthe hopper and raceway havebeen proposed in machines of this general type. but none is entirelysatisfactory, especially in view of the time involved in effecting;removal of the tustenings. Although it is seldom necessary to change thekind of fastenings in such ma chines in ordinary shoe factory. use sothat the amount of timecons'umed in such an operation is not a matter ofimportance, in the use of such a machine as a shoe repairmw chine itvery frequently becomes necessary to change the kind .of fasteninejs tosuit the work offered for repair. Under such circumstances it ishigrhly'desirable to be able to obtain suitable fasteningsat the point offastening insertion, as the characterof the workchanges, with theminimum expenditure of effort and time. 7

The present invention is disclosed herein as embodied in a machine ofthe type disclosed in said Letters Patent No. 490,624, though it shouldbe noted that in various of its aspects it is not limitedto useinconnection witha machine of that type.

It is an object ofthe presentinvention to proride improved. means forsupplying fas- 1918'. serial No. 237,418.

Theconstruction for efl'ectingthe operative connection referred toisxofasuch a character that no OlDSlZlLlCtlOHilS offered. to themovement of the'l.magaZine-and-race-- way'unit into its proper positionon the machine frame;

In, one aspect of the invention, important features consist in anorganizationlby which suitable fastenmgs maybe obtained,readily at thepoint of fastening:insertionsimply by selecting: the fastening-supplylngun1t containing the desiredfastninQs and almost;

instantaneously attaching said unit tothe machine.

A further feature of relates to the construction of the lower end of theraceway and of the nail throat. Ordinarily the throat and the racewaypresent projecting surfaces some or all of which have to be ground downrepeatedly in securing the proper fitting together of these parts at thetime the machine is assembled. Moreover, a fine degree of adjustment isusually required in positioning the raceway in proper fastening deliveryrelation to the nail throat. The raceway and throat disclosed herein arecharacterized by marked simplicity in construction and by the ease withwhich they may be assembled in proper fastening delivery position.

In order that the interchangeable fastening supplyingunits may bereadily accessible at all times, a specially constructed bracket ismounted on the standard of the machine and is provided with means forreceiving and holding each unit so that it may be readily removed andreplaced. on. the bracket.

Other important features and objects of the invention will appear fromthe following description and claims when considered in connection withthe accompanying drawlngs.

9 is a View in detail of the deliverv end of the raceway with thefastening retaining finger withdrawn from the slot of the raceway.

For the purpose of illustration, the invention is shown as applied to amachine of the type disclosed in the patent to Goddu re ferred to above.The chief features of construction of this machine are found in theoscillatory or swinging head 6 which carries the driver bar 8 and theawl operating mechanism 10 for causing the awl 11 to penetrate the workand feed the same overthe horn 12 in proper position for the insertionof the fastening by the driver 14. In order to supply fastenings to thethroat 15 of the inserting mechanism, there is provided a magazine 16and a raceway 18 which, in accordance with the present inven-- tion, areformed preferably as a unitary structure arranged to be detachablysecured in position on the machine frame. its the fastenings reach thelower end of the raceway they are separated one by one and shoved intothe throat or nail guiding passageway by means of a separator 20operated. from a lever 22 as clearly disclosed in Fig. 2 of thedrawings.

In order to secure the magazine-and-raceway unit 24 in proper fasteningdeli rering position on the machine frame there are provided on the unitand. on the machine frame interengaging securing and positioning memberscomprising, in the preferred form, a forked member 26 designed to engagethe headed member 28 as the magazine-and-raceway unit is moved bodily,sidewise into position. After the members 26 and 28 are properlypositioned relatively to each other the handle 30 is turned in onedirection to cause the eccentric 32 to move the clamp member 28downwardly, thus firmly clamping member 26 on the support 34, a spring36 being provided to assist in releasingthe clamp member 28 as thehandle 30 is turned in the opposite direction. An additional securingmeans is provided preferably in the form of a rod 88 fixedly secured tothe upper end of the magazineand-raceway unit and designed to be clampedin the split collar 40 upon proper manipulation of the adjusting member42. The split collar 40 and the clamping member 28, 34 are carried upona bracket 44 fixedly secured to the oscillatory head (3. Adjustablysecured in this same bracket 44 are two positioning members 46 which areoperative to engage the magazine-andraceway unit at two widely separatedpoints on the surface thereof to limit the movement of the unit inwardlytoward the machine frame and thus, as gages, to determine the properfastening delivery position of the unit. In order to furnish support forthe free end of the bracket 44, that is for the end unattached to theoscillatory head. there is conveniently provided an extension 48 on themain frame 50 of the machine, the said extension carrying looselypivoted thereon a rod 52 arranged to telescope with a portion of thebracket 44 as clearly disclosed in Fig. 2 of the drawings. Freelymovable means of support for the outer end of the bracket is renderednecessary by the fact that the bracket is carried by the oscillatoryhead as already pointed. out. It will be obvious that in placing themagazineand-raceway unit in proper fastening delivery position in themachine it is necessary only to see that the forked member 26 is engagedwith the clamp member 28 and that the member 38 enters the collar 40,the clamp member and IOU llt

.llii

collar acting not only as securing means but as guiding means while theunit is being moved sidewise into engagement with the positioningmembers 46 which limit the movement of the unit and determine its properposition on the machine frame.

When in proper position manipulation of the handle 30 and the hand wheelat? operates to secure the magazine-and-raceway unit fixedly inposition.

While the raceway structure is being moved into proper fasteningdelivery position, a spring member 53, having a fastening retainingfinger extending across the delivery end of the raceway, is moved bycontact with the front face of the nail throat to cause the withdrawalof the finger 55 sec Fig. 9 thus permitting the fasteninigs to come intocontact with the fastening separator 20. lVhile the magazinaandmacewaystructure is being removed from the machine, the spring member 53returns the finger 55 to a position to retain th fastenings in theraceway. In the present embodiment of the invention, themagaziifle-andraceway units are designed to supply each a different sizeof fastening from those supplied by the other units. Inasmuch asfastenings may differ considerably in length while varying but little inwidth or thickness of the shank, the same separator 20 withoutadjustment may be used to separate the fastenings' supplied by thevarious magazine-and-raceway units designed, as in this case, to supplyfastenings of various lengths for repair work.

The raceway 18 is detachably secured to the magazine and raceway unit 24by bolts 56 which ass through openings in the raceway of greater sizethan the diameters of the bolts in order to permit the raceway to beadjusted relatively to the remainder of the unit 24. Vertical adjustmentof the delivery end of the raceway 18 may be effected if desired by anymeans suitable or usual for this purpose.

Preferably the magazine and raceway unit comprises a hopper 54,stationary with respect to the raceway, and a rotatable magazine 16, thelatter being operated by a shaft 58 carrying a disk 59'having a slot 60cut through its periphery and extending relatively near to the center ofthe disk. liflonnted upon the raceway is a raceway clearer 62 arrangedto be driven from a shaft (5-41 carrying an arm 66. 'l Vhen themagazine-and-raceway unit is shoved into position on the machine framethe disk 59 will engage the face of a co-operatingdriving member 68carried at the end of a shaft '70 driven by mechanism hereinafter de-'scribed. In order that there may be noobstruction to the movement of themagazineand-raceway unit into contact with the-p0 sitioning members 4L6the pin 72 is yieldingly carried by the member 68 as clearly disclosedin Figs. 2 and 3 of the drawings wherein a spr ng 74 is shown in contactwith the rear face of the pivoted block 76 wh'ch carries the pin 72. Viith the magazine and raceu' 'ay in position, rotation of the shaft andtherefore of the member 68 will cause the pin 72 to move over the faceof the disk 59 until it finally engages the slot 60 thus effecting anautomatic connec tion between the driven shaft 70 and the shaft 58, andin this way providing for the rotation of the magazine 16. Mounted inthe frame 50 is a short shaft 78 which is arranged to be driven from thesa1nemech a- HlSD') that causes rotation of the shaft 70. An arm 80mounted upon the outer end of the shaft 78 carries a pin 82 so arrangedas to contact with the arm 66 on the clearer shaft 64% to causerotation, of the clearer 62. Shafts 70 and 78 carry pulleys 84 and 86,respectively, connected by belts 88 and 90 to pulleys on th shaft whichcarries the large gear 92, the latter being driven from a small gear on;the main shaft of the machine as disclosed in said patent to Goddu Itwill be apparent from the description that operative connections areestablished between the rotatable magazine and. the raceway clearer andthe driving means for the same at the moment that th magazine-andracewaystructure arrives in proper fastening delivering position of the machineframe, and that thisis' accomplished with out any attention or effort onthe part of the operative engaged in assembling the selectedmagazine-and,raceway structure with the fastening inserting machine.

it feature of importance which facilitates the adjustment of thera'cewuiyand contributes to the ease with which the magazine and-racewayunit may be assembled with the machine is'found in the construction ofthe lower end. of the raceway and the nail throat where thesetwo'i'nembers come into contact with each other. As showm .in Figures 6and 7 of the drawings, the lower end of the raceway consisting ofprojectingportions J4- and 96 presents a plane end surface adapted toslide smoothly over a plane surface on the nail throat 15. the latterbeing a continuation of the driver guide 98. Because of the constructiondescribed the eno'of' the raceway may be moved or adjusted in anydirection while in contact with the plane surface 100 of the nail throat15. Thus it is possible to adjust the lower end of the racewayvertically with respect to the separator 20 so as to bring the separatoras near as possible to the head of the fastening. Moreover, the lowerend of the raceway may bereadily adjusted so as to bringfthe slot 102ofthe raceway into proper alinement with the passage or slot 104 in thesurface 100 leading into the nail passage in'thenaii throat. Asheretofore constructed, the lower end of the raceway and the nail throathad projecting portions which had to be carefully fitted together, thusmaking adjustment in both vertical and lateral directiojs difficult tocarry out and, if the adjustment between the raceway and throat were notproperly made. the fastenings in the raceway would fail to be deliveredproperly to the nail throat with the result that fastenings might bejammed in the passageways, thus reducing materially the output of themachine. In the construction herein shown a further feature ofimportance disclosed in Fig. 7 consists of the provision of a wide slotthrough the surface 100 of the nail throat which slot leads into thenail passage at the throat and is practically as wide as the diameter ofthe circular passageway. Inasmuch as the slot 102 in the raceway isconsiderably narrower than the slot 10-1 it is correspondingly easy tomake the proper adjustment of the raceway since the median line in slot102 does not have to coincide with the median line in slot 104 but canbe displaced to one side or the other thereof to a substantial amountand still deliver the fastenings properly into the nail passage of thenail throat. Conveniently, the nail head supporting surfaces of theraceway are beveled off at their lower ends as disclosed in Fig. 7 topermit the fastening to drop slightly as it reaches the lower end of theraceway, thus bringing the nail head nearer to the upper edge of theseparator, this ar rangement having the advantage that the fastenings,and particularly the shorter fastenings, are moved more surely into thenail throat and kept in proper alinement with the throat while being somoved. 0

As clearly indicated in F 1 of the drawings, a plurality offasteningsupplying units is provided for use with the machineconstructed according to this invention, to enable the substitution offastenings of one kind for fastenings of another kind whenever it maybecome desirable or necessary by reason of changes in the nature of thework being operated upon. It will be obvious that fastenings of variouskinds, or more specifically of various sizes, may be delivered tofastening driving position by selectively using the interchangeablefastening supplying units provided with the machine and shown supportedin a location readily accessible to the operative so that a change infastenings may be made with the minimum expenditure of time and energy.The support for the magazine-and-raceway units is shown in Fig. 1 toconsist of a bracket 106 conveniently secured to the standard 108 of themachine, the said bracket carrying a plurality of auxiliary brackets 110each designed to support a single magazine-and-raceway structure 24.Each auxiliary bracket. 110 comprises a concave seat 112 adapted toreceive the convexly curved surface of a magazine 16. Each said bracketcomprises further an abutment 11 1 notched as shown at 116 for thereception of the lower or rear edge of the raceway. Thus, when amagazine-and-raceway unit is placed upon its individual bracket with theconvexly curved surface of the magazine resting in the seat 112, thesaid unit turns rotatably in the seat 112 until the lower or rear edgeof the raceway contacts with the notched end of the abutment 11 1, thesaid abutment thus serving to limit movement of the unitary structure inthe seat 112 and also to hold the structure against displacementlaterally in the bracket.

It is thought that the manner of using and operating the variouselements in which are embodied the important features of the inventionwill be obvious from the detailed description of the construction asgiven above and that no further description thereof is necessary.
